IMPROVEMENT IN PETROLEUM-Noves.

Specificationl forming part of Letters Patent No. 48,732, dated July 11,1865. i

To all .whom it may concern:

Be it known that I, HAMILTON E. SMITH, of Cincinnati, Hamilton county,Ohio, have invented a-new and. useful' Petroleum-Stove; and I do herebydeclare the following to'be a `full, clear, and exact descriptionthereof, ret' erence being had to the accompanyingr drawings, makingpart of this specilieation.

My invention relates to a portable cooking apparatus to be heated by'aseries ot' petroleum or other hydrocarbon lamps, the various boiling,baking, and other compartments being capable of being operated, eithersepa rately or in conjunction, by the use of one or more lamps, vas maybe desired.

Figure lis a perspective view ot a stove Fig. 2 is a vertical sectionthereof.

A 1s a reservoir for petroleum, coaloil, or other burning-fluid.

B B B B are lamp-burners of' any approved construction.

Instead of the customary glass-chimneys, I provide chimneys C, of sheetmetal,` which chimneys may be bulged opposite the liame,

',chamber and independent burners-#one or and may taper upward anddownward. Each chimney is furnished with a window, D, of mica, which,affording a view of the llame, en-

` ables the operator to know whether to elevate or depress the wick.

E is a stand provided with racks F for supporting ata suitable heightabove the burners anoven, G, and boilers or kettles H and I. The oven Ghas two circular apertures, J J', i'n its bottom plate immediately overthe chimneys .of the -two central burners, a small interval in heightbeing left between said chimneys and the said plate to enable the spentand cooled air to escape from the oven, so as to provide room for theheated emanations from the burners. The interior ofthe oven is soarranged as to be capable of being separated into two compartments by avertical plate or Y partition, K, and each ot' these compartments isagain divided into sub-compartments 'by meansof floors or horizontalplates L. Vertical division and horizontal subdivision is represented inFig. 1. The said mode of division enables the use of one side only ofthe oven when a small amount ot' cooking is to be done, thus economizingfuel and avoiding ex- This The plates K and L are retained y in theirplaces by flanges M on the interior surfaces of the oven, and arecapable of being withdrawn entirely, so asA to leave the entire interiorot' the oven unobstructed; or the plateK may be used fora horizontaldiaphragm, as in Fig. 2.

in the boiler.

S is a water-pan supported on perforated flanges s, for insuring-a freecirculation of heat around the pan.

T is a perforated plate or grid for cooking meat, fish, dic.

It will bev seen that the separate hot-air more to each chamber-enablethe optional use of one or more departments of the baking and boilingapparatus.

I claim herein as new and ot' my invention- 1. The series of petroleumor coal-oil burners B B' B" B, in connection with-a corresponding numberot'scparate hot-air chambers or receivers, Gand N, having venta ges forspent air at their bottom por-tions only, substantially as set forth.

2. In connection with two or more independent burners, B B', the oven G,capable ot' vcrtical subdivision, in the manner and for the purposeexplained.

3. In the described combination, with a petroleum-stove, ofthe tubularhot-air'chambered boilers, whose ventage for thespent air is at thebottom otl their chambers, as set forth.

In testimony of which invention I hereunto set my hand.
